Subject: VintRR BSA/TRIUMPH TRIPLE TH6 CAMSHAFT TIMING
I am trying to time the full race camshafts of my friends Rocket 3
vintage racer. I have a leaflet from Norman Hyde which states valve
lift at TDC on overlap at .230/.245 thou for inlet & .175/.190 for
exhaust (from memory). With a dial gauge on the valve collars the
readings are .020/.030 too low. Advancing the timing pinions one tooth
opens then too much. I gather I have to put the pinions back on the
cams using one of the three different keyways which will alter the
lift in smaller increments. (One tooth equals 15 deg, each keyway 5
deg. change) Do I put the camshaft at the correct valve lift & the
crankshaft at TDC & then use the best tooth/keway combination? Does
anybody have the opening / closing figures with valve clearances
stated for these cams?
Maybe if I dont get this done correctly I will be able to beat him at
the first race of the year tee hee!

In short, yes.

If using these out of date and nasty cam forms I always use the old
favorite figues, of lobe centre inlet 98 ATDC, and exhaust 102 BTDC
Clarances suggested are .005 inlet .007 exhaust
One set of quoted open/close figures, at unspecified follower lift are:
43 dtc / 59 abc
63 bbc / 39 atc
Hope this helps.

Tim Harris asked:
>>What year did they first put Disk Brakes on the 350 CB Hondas????<<
It was the last year. It was known as the CB350K5 or CB350G. The next year we
got the CB360, proof that "progress" frequently amounts to making things
cheaper, rather than better. And as a relative sales flop, that manufacturers
need to provide some high tech razzle-dazzle to distract the buyer from the
throwaway nature of his new toy.
But what was that year? 1974 I think for the last 350, 1975 for the first 360.
Or am I off by a year? If so, which way?

Subject: VintRR Vintage Race Report
Hey All:
I know an Ascot is not really a vintage bike, but it's eligible for WERA
Vintage, so what the heck. For the terminally bored, here's my race report from
Summit Point. I'll spare you and only report on my Vintage race on Saturday.
If you're a real glutten for punishment and want to read about my Clubman and
Twins adventures on Sunday, check out my web at

SUMMIT POINT, WV -- April 12-13 -- Id heard the lore of Summit Point -- or
Scummit Point, or Slippery Point, depending upon who you talk to. Stories of
non-existent traction, a racing line six inches wide, a surface so polished that
you can actually be blinded by its reflection late in the day. Mention the word
rain¶ in the same sentence with Summit Point, and the locals just look at you
with a somewhat maniacal grin.
So it was with a fair amount of trepidation that I headed to Summit late Friday
night with two racing buddies for a WERA regional race weekend. One buddy had
cut his teeth racing at Summit, and the other, also a local, had turned quite a
few laps on the track in race cars. They spent much of the trip recanting Summit
Point lack-of-traction horror stories. Factor in the same from our DC-based
friends we hooked up with at the track, and I was convinced that just remaining
upright in the pits might be an accomplishment. However, with a AHRMA National
being held there May 3-4 (with no Friday practice day -- something tells me you
guys will be hearing about that at the rider's meeting, John G.) it seemed like
a good chance to acquaint myself with a new track.
After a leisurely three hours of sleep at Seans parents house, we hit Summit
about 7 a.m. Saturday. The first practice session didnt seem bad. Armed with
the advice of never, ever, ride anywhere but the concrete patches in the
corners, the Mighty Ascot (tm) and I felt our way around the track. Fun layout,
not too bumpy, and the section of the track (three corners) that had been
repaved was actually quite nice. The bike was running well, and I was looking
forward to the days Vintage racing action. That is, until the rain drops
started hitting my shield in the closing laps of the session.
Great. Im already psyched out about the track in the dry, and now its
raining. And here comes more stories about people crashing, even while simply
riding down the straightaways. So, now swathed in my $10 Yamaha rainsuit, I
prepared for my second and last practice session of the day. First problem --
the crotch of my rainsuit blew out when I swung my leg over my bike. I lost
weight over the winter, but I guess not where it counts :-) Second problem --
pouring rain, wet tires, and wet metal starting rollers are not a good
combination. No traction, no starting. Third problem -- wet tires and wet
asphalt are almost as slick. A few runs and well-timed drops on the seat got
the fire going, and after my heavy breathing stopped fogging my shield, I headed
out for practice.
Naturally, in the very first turn, a rider crashed in front of me, going maybe
20 mph. I filed that in my brain for a data point (do not exceed 20 mph in turn
one¶). Unfortunately, after one lap my mind was full of data points as people
were slithering off the track left and right. I now only had one brain data
point -- do not crash in practice; if you must crash, at least save it for the
race.
My race, Vintage 4, was the first race of the day. As I rolled to the line
after yet another shield-fogging bump start, it was raining with a monsoon-like
intensity. The starter, who had spent at least 20 minutes during the riders
meeting explaining exactly how the starting procedure would take place,
proceeded to completely ignore his own instructions, catching nearly the entire
grid, myself included, with our shields up and bikes in neutral. Despite the
surprise start, I still tiptoed into the first turn in second place, and
immediately took the point when the lead rider crashed. Me lead was
short-lived, however, as I was passed while cautiously exiting turn two. That
rider -- and as Dave Barry would say, Im not making this up -- then proceeded
to crash in front of me ON THE STRAIGHTAWAY!
It had now become obvious to me that, despite riding like a complete weenie, I
was on the threshold of physics. Like the speed of light, nature was dictating
that the Speed of Mark could not be exceeded. Try, and the ground would rise up
a smite thee.
The race was unfolding like a Laugh-In skit -- riders were falling left and
right. A torrential river of mud and water flowing between turns seven and
eight claimed more than a few bikes. (I discovered that, like in cattle drives
in the Old West, you merely needed to enter the river at a point upstream of
where you hoped to exit.) In fact, one rider fell victim to the river directly
in front of me. Due to the low speeds, he didnt even slide off the track.
Realizing he was laying on the racing line, the rider was furiously attempting
to crawl to safety. However, the lack of traction basically had him spinning in
place, like a cats initial acceleration on a hardwood floor. My eyes tearing
from the laughter, I managed to avoid him and not crash myself.
Okay, at some point in the race (which was shortened to four-laps -- the longest
four laps of my life) some guy -- who obviously didnt pay attention during
physics classes -- did manage to flaunt Marks Law, pass me, and not crash. He
was riding a BMW, and I have theorized that perhaps the cylinders acted as
outriggers or pontoons.
So after, four stress-filled laps, I managed to remain upright and finish
second. In fact, out of about 12 starters in my class, only two finished! Its
usually not too thrilling to see your name listed last on the result sheet, but
instead of washing mud off my bike, leathers, and repairing crash damage, I got
to prepare for the next day of racing with a fine Italian dinner.

My Honda MC Identification Guide shows the CB350G with a disc brake.
Sell Date 1973, Release date 01/01/73.
CB360G is model year 1974. That year also had a CB360K0 with a drum.
The Honda single piston brakes were not particularly wonderful units.
I'd swap one for a cast iron RD brake in a second.

Subject: VintRR oversize pistons
I have my question for the day. I have a 1975 CB-400F which I race in
vintage. I am always looking and thinking ( sometimes too much ), how
to make it faster with parts from other models. Now the fun part. I
want to use a big bore kit and would like to use pistons from another
Honda model ( besides CB-500F ). I was thinking around a 54 or 55 mm
Dia. piston would be just about right, with a high dome to aid
compression.( the 500 pistons are flat tops). Does anyone know of
such a beast?. In additon I found that a piston from a 1989 CB-1
honda has the Dia, ( 55mm ) weight and modern rings I like but the dome is not
high enough and the valve recesses are too deep. Has anyone heard or
know of someone who can build up the top of a piston so it can be
remachined to the needed shape etc. Last but not least Thanks to
everyone out there who has replied to my questions in the past, if
you have your own ideas on how to make a 400f beat the dreaded two
strokes I would love to hear them. And if you ever come accross an
old 350f or 400f race part or bike keep me in mind. Long Live the
Screaming Fours. Darrell

Hello Darrell,
Get yourself a Wiseco catalog and start by looking at all the pistons
with the same wristpin size. A stock 400 uses a 13mm wrist pin, and
as I recall when I bought Carillo rods for the 350/4 racer Craig
recommended going up to 14mm on the wrist pin size. The GPZ550
Kawasaki uses a 14mm pin but is a 58mm bore (this is what I use in my
CR216 Honda). A stock XR100 piston is 52mm bore with a 14mm wrist
pin (what I'm using in the 160 trials bike) and has a flat top with
minimal valve notches. A 1mm oversize brings you close to the size
you are looking at. There doesn't seem to be a big selection in 14mm wristpin
pistons.

A high dome is the LAST thing you want to use, especially one made
by welding on a piston. Run a flat top piston and have someone weld
up the combustion chamber to get the compression. You'll have less
heat losses into the head and piston due to the reduced area, a
lighter piston, a shorter flame front, and plenty of squish area
between the piston and the head.

You need a good ignition, and start off with somewhat less advance
than stock (if you weld up the chamber you'll probably be able to get
away with about 28 degrees total advance timing). Don't get suckered
into excessively large headpipes - certainly no bigger than 1.25" OD
- - and my CR216 runs pretty well with 1" OD pipes. Check around with
your local Guzzi riders and get a set of 30mm Dell'Orto carbs. Due
to a rule change that I still haven't heard a convincing arguement
for, the CR Kei'hins which are historically correct for your bike
aren't legal (the no integral-float smooth bore rule).
Get some real front forks and shocks, and ditch the Honda disc brake
calipers. The frame can benefit from some bracing, and bronze
swingarm bushings are also a good idea.
If you are building a 500, Craig has told me that in many ways he
feels the CB500 is a better way to go than a big bore 400 - but then
you've already got a 400. He can do anything you need to get a 400
going quickly - how about a nicely lightened and rebalanced
crankshaft to go with the Carillo rods the bike needs to live?

Michael

Michael is correct, as even Jim Reed (who wrote a really thorough and
excellent series of articles on race preparation of R's/RD's) prefers the
stock, cast RD brake. If I remember the articles, the more 'trick' race
brake had a bad habit of disintegrating. Once is enough. Anyway, it follows
with the 'cheeseburger' theorem. Just eat one less a week, and the weight
difference will be compensated for adequately. Some of Reed's
recommendations vault the simple and relatively affordable R project into
the next $$$ level, but -then- that is a matter of choice just how far one
wants to go, literally and figuratively.
Of course, one can go nuts and get a 4ls racing drum from Japan or Italy
for $500 and going north fast!
I have a friend in the next town over who has one of the drum CB 360's.
Nice competent little bikes!

Hello Jay,
Everything I heard in re the RD vs TZ caliper was that the RD
caliper was more rigid in use - the TZ aluminum caliper would flex
under heavy use. I saw a number of TZs equipped with the RD caliper
instead of the original aluminum unit. My friend Craig made
patterns and made some aluminum copies of the RD caliper for a while
shortly after the RD came out, but I don't think too many of them
were made or sold. The were marked "Grizzly" as his shop was
Grizzly Engineering.

Ed, the s_r I see is just a true vertical line for use to compare
against the top and bottom sides of the wheel to see if the wheel is
also vertical.
Let me think and see if I can come up with some alternatives for you.
Do you have access to a vertical milling machine or something else
with a nice flat surface, preferably with a hole or T-slot in it?

No idea as to the specific technical issues involved. However, my first
race is next weekend at Loudon. If the individual is there, I will ask
him and let you know. The tuner's name is Seppo Suovo. Greg Nichols was
riding for him. You may know one or both of them.

Subject: VintRR Tire questions
Hello people, I have a couple of questions, hopefully, they are not too
neophytish.
The first is, what do racers use to balance your tires? I have been using
lead solder successfully for my street bikes and can't think of a reason not
to use it on my (still being put together) 750 Norton, to be used as an
AHRMA racer. Any comments?
The second is mostly just a point of discussion. John Goodpaster wrote in
the April issue of Vintage News to use metal valve caps that have the rubber
gaskets in them. Evidently, some metal valve caps do not have the rubber
gaskets and at speed the valve stem collapses and permits air to escape past
the valve cap and without a sealing washer, causes a flat tire. Wow! That
is hard for me to believe, although coming from John G., I surely can't
argue. Any comments? Any tube brands to stay away from, or good tube
brands to buy?
That's all the questions for now.
Thanks everybody,

Subject: VintRR 90 Deg Norton crank
Thanks for all the replies so far, but nothing substantial, One person
has already gone this route Brian Tyree, & another with a 60 Deg
crank, both who I shall contact personally.
The reason for 90 & not 180 is that when the pistons reach TDC or BTC
they want to stop, with a 90 Deg crank one piston is nearly at its
maximum speed & this stopping action will be reduced (Phil Vincent
suggests 76 deg, but this depends on the stroke of the engine, when
the rod is at right angles to the crank).
An added bonus is that all the secondary forces are canceled out (they
occur at twice crankshaft revs in different directions with a 90 Deg
crank). Yes I know there will be some rocking couples, but I dont even
know where to start in canceling them out, but I'm sure they are a lot
less that a 750/830/920 parallel twin!
I am thinking of a balance factor of 50% & the engine will be mounted
in a featherbed frame, the isolastics only work in a one directional
plane (up/down front/back) not with rocking couples.
Please keep the ideas coming.

Why 90 degs? I would have thought a 180 deg crank would have offered a
smoother ride. Didn't the early Jap twins have this set up? This has all
the hallmarks of being the most interesting discussion on the list in a

I may be some what off here but it could pay off to look at small bore
Honda single dirt bikes as donors - some very fast 500/4's were built
around these
or old twins like 150 160 cb72 77 where you may find more domed pistons

Don, thanks for the tip, you maybe very right. Ther was a 400 racer
built in England not too long ago and they used pistons from a 125
single, the problem is that I do not think this was a model that was
ever imported into this country or the U.S.. Darrell.
To the person building the 350 Honda twin racer, the best place I
know of for race parts for the twin would be Todd Henning in Boston
he has great pipes pistons etc. etc.. The worst part will be the cost
I am afraid, but if you would like his address and phone number I
will pass it along if you would like it. #62 AMCRA

Not sure about deck highth, wrist pin size, ect. But, the 125 twin
piston might be a way to go on this. The CB72 piston size is 54 MM, very
early CB72's used a 10.5 compression ratio. Ellis

Hello Ray.
I will try to get Seppo Souvo's address & phone # for you or maybe Chris
can remember. Seppo has set up some of the most ferocious,
track-scratching Nortons I have seen. He has a 750 that Greg Nichols rides;
while Greg is an excellent, aggressive rider, that Norton can burn up the
track and hold its own with anyone. As far as I can remember it has a 5v
close ratio gear box and the usual and unusual mods. Maybe John Goodpaster
has some suggestions re Nortons.
As for tubes... the best is the cheapest in the long run. If you are going
to flail yourself and this road hungry Norton what's a few $$$ versus your
life. I have always used top brand stuff even on the street... Avon,
Dunlop, Michelin, etc. I am relatively new to recent vintage racing but did
alot of spec. before I got started & have seen various approaches, when it
comes to weights. If you use the self-sticking rim weights, cover them with
a bit of >>>>good quality <<<<< racing tape. If you use crimp/spoke weights
either girdle them with lockwire or a bit of racing tape or both, both is
nice. The trick appears to be making sure they remain on the bike vs. the
track. Per weights, John G. would know best or Chris Stein who used to tech
bikes...
I used to do alot of dirt-biking years ago; I even lock wire the spokes to
each-other where they intersect. While I don't go really fast, I feel just
that bit more secure. Being anal works just fine. JC Whitney's sells a very
acceptable pair lock-wire pliers for around $20.00
Good Luck & have a blast. Nortons are absolutely neat bikes. They look and
sound wonderful throbbing around the track. The roadholder fork may be 'old
hat', but it really does a good job.

An excellent exhaust builder(F1200/1600/2000, Stock car, vintage & modern
bike) is Wolf Racing in Cambridge. Gary used to mass produce those Wolf
headers in the early eighties. He's made quite a few pipes for some pretty
fast 350's (including Todd Henning's). If you're at any of the races you'll
see them.
Clip-ons for smaller fork diameters can be found through Waldridge Motors in
London(he specializes in british bikes but is a good source for vintage
stuff like tires, aluminum rims, ignitions, shocks etc.)- matchless@std.net
I run a '72 350 in Period 2. It was period 1 legal in '95 when you were

Frankly I do not see how something that weighs less then a gram,
held by a spring and 30 psi behind it can be forced open. I can only assume
that the spring is weak. I do know that the weight increases due to the
centrifcal force and then becomes much heavier overcoming the spring
tension. The valve cores with the internal spring seem to be stronger. I
think Metzler, Continental, Michellen and Dunlop tubes are the best. They
cost more then the others but are very good quality

Try Walridge Motors in Hyde Park, Ontario. They are primarily a supplier
for Brit bike parts but have clipons etc in their catalogue. They can also
get Swarbrick exhaust systems from England. (519) 641-2770. Check out
last month's Cycle Canada for an article on vintage racing with lots of
pictures to show you what the bikes look like. If you're near Toronto,
Jammie Cummings has just finished a nice CB350. He would certainly let you
have a look at it. (416)264-2960.
I made my own megas out of the original mufflers then sanded down the
chrome and painted them black. They work very well. A pair of Swarbricks
for my bike costs $220 CDN. Those are next on my list to purchase.
BTW I took the new engine (CB450) that I built over the winter out to
Shannonville last weekend for the test days. Apart from a few small
gliches it ran great. Took it easy all day breaking it in then let it rip
down the back straight at the end of the day. Stayed with a CB750 the
whole way down the straight. YeeeeeeeeeHaaaaaaaaa.

My friend Peter has one of the CR110 street bikes - rough condition

Subject: VintRR A REALLY dedicated racer
Mario Columbo's "Moto Guzzi" has a somewhat macabre story about the
pre and post-war Guzzi racer Omobono Tenni, a racer who's riding
style seemed to defy the laws of physics (as did his ability to
survive some lurid crashes). I'll paraphrase some comments from the
book:
An interesting anecdote involved a crash during practice at the
Circuito del Lario. Tenni had to go off the road into a ditch in
order to avoid colliding with a horse and cart (obviously an open
roads course). There he remained until worried race stewards mounted
a search for him. He was found half-unconscious with pain, groping
around in the grass for bits of his finger bones, which he was
placing in a handkerchief convinced that the doctors would have been
able to put the bits together again.
Another escapade occured at the 1935 Isle of Man TT. During practice
while steaming down Bray Hill on the 500cc wide-angle Guzzi V-twin he
strayed too far to the left and wound up in a ditch, but he blithely
carried on for twenty or thirty yards before he got the bike back on
the road under the horrified gaze of the spectators, all of whom were
convinced that he was bound to break his neck. ".... I could have
got her back on the road sooner", he was to say afterwards, "but
seeing I was in there I thought i might as well see how well she
handled off the road . . .". Another competitor who had been
following him told the press that Tenni had shaved the embankment so
close that he had torn out lumps of earth with the handlebars.
I think I'll play things a bit safer on the track, thanks very much.

have known a US hot rodder). Of course, there was Dick "Bugsy" Mann
and David "Rubberman" Aldana. I think that Renzo Pasolini may have
had the nickname "Knees" from his knees-out riding style.
Anyone else recall some interesting nicknames?

Well USCRA held its first event of the season, 5/3/97 & 5/4/97, in
conjunction with the LRRS. It rained a good portion of the time, but Sunday
blew clear. As always, the track was well managed and well run by the US
Marshals - no surprise. On Saturday, I raced with a few other stalwarts (I
come from a place where the men are men and the sheep are nervous!) - the
last turn onto the oval - down. It was slicker than ice just wet from a
Zamboni; there went the new rain suit, crunched clutch lever, a few file
job motifs on the left points cover &c., and a bent shifter - got lucky.
Some people had the great sense to remain garaged. Sunday was much more
fun. I finally have sorted out the jetting - no mean feat for a 4-stroke
person.
The only unfortunate incident was that Chris Stein droped his
verrry, verry lovely ice-blue RD 350 into Turn #3, It is perhaps one of the
more attractive racers I have seen - -. It was a treat to be garaged with
such a lovely bike. He is an absolutely spotless rider, so a double shame.
I went by wanting to stop and commiserate ( real competetive, hunh!). Turn
three comes off the oval and switches right up a rather steep incline. It's
quite fun, but it seemed to eat several bikes this weekend, being the turn
of choice for such things.
I had a great time dicing with a Norton Commando (there were
several waves/classes at the same time). Riding a Commando on the street, I
just knew where he was going to torque out. The little R-5 was great in the
corners and ok on the straights, but the Norton was a champ on an uphill
pull.
If any of you classic racers from other parts of the country want
to have fun, come join us at Loudon in June for the two classic events. The
sidecar race is always fun to observe. I am now off to a of dog-show -
talk about cutthroat and competetive.

Okay, not quite.
I know I 'm going to be looking for a new truck by the end of the summer,

So the questions are: Which minivans will take racebikes? streetbikes?

If you must have a small van - Astro/Safari get my vote used one for
4yrs - best load carrier -tow rating- prob worst mileage -- give
aerostar 2nd place
a friend used one for years - overhead door is a drag - carries less
load - gets better mmileage - we both use full size now Your mileage may
vary - don

A friend used to put his BSA b-50 roadracer in his Ford Aerostar. The
front wheel of the bike came forward almost between the driver's seat,

From the strange and bizarre world of real life:
------------------------------------------------------------
Here are some highlights of ER admissions to Chicago General
over the past year:
- A 28-year old male was brought into the ER after an
attempted suicide. The man had swallowed several
nitroglycerin pills and a fifth of vodka. When asked about
the bruises about his head and chest he said that they were
from him ramming himself into the wall in an attempt to make
the nitroglycerin explode.
- A woman with shortness on breath and who weighted
approximately 500 lbs was dragged into the ER on a tarp by
six firemen. While trying to undress the lady, an asthma
inhaler fell out of one of the folds under her arm. After
an X-ray showed a round mass on the left side of her chest
her massive left breast was lifted to find a shiny new dime.
And last, but not least-- during a pelvic exam a TV remote
control was discovered in one of the folds of her crotch.
She became known as "The Human Couch".
- The most nonemergent ER visit: A male adolescent came in
at 2 a.m. with a complaint of belly button lint.
- A 92-year old woman had a full cardiac arrest at home and
was rushed to the hospital. After 30 minutes of
unsuccessful resuscitation attempts the old lady was
pronounced dead. The doctor went to tell the lady's 78-year
old daughter that her mother didn't make it. "Didn't make
it? Where could they be? She left in the ambulance
forty-five minutes ago!"
- A 15-year old boy was laying on a stretcher with his
mother sitting next to him. The boy was coming down from
"crank" (methamphetamine) that he had injected into his
veins with needles he had been sharing with his friends.
Concerned about this the doctor asked the boy if there was
anything he might have been doing that put him at risk for
AIDS. The boy thought for a while then said questioningly
"You mean like having sex with our dog?"
- A 19-year old female was asked why she was in the ER. She
said that she and her boyfriend were having sex and the
condom came off and she wasn't able to retrieve it with her
fingers. She went to the bathroom and "gagged myself to
vomit but couldn't vomit it up either."

Subject: VintRR Summit AHRMA report
Hey folks:
Here's my race report from the AHRMA Summit Point race this past weekend. I
know, I know, a Honda Ascot isn't *exactly* a vintage bike, but it WAS a vintage
bike race, and the traffic's been pretty light on this list, so here it goes:
SUMMIT POINT, WV -- The AHRMA road show rode into town here just one week
following the AHRMA Willow Springs race in Southern California. Turnout seemed
lighter than usual, although that may be more attributable to Summit Point's
"stellar" reputation in the racing community than the bi-coastal scheduling.
My previous trip to Summit a few weeks back had taught me all you need to know
about Summit -- don't get off the concrete patches in the corners, and pray it
doesn't rain.
Saturday dawned breezy and cool. The weather forecasts were iffy, and, coupled
with my four hours of sleep in the passenger seat of the van, I wasn't feeling
too chipper. Dennis, our buddy from DC, showed up with his Krups cappuccino
maker, and a double mochaccino got things looking up.
Morning practice sessions showed the track to be slick (imagine that), and my
times were a few seconds off my race times of three weeks back. Racing on the
"rain groves" through third-gear Turn 9 and fourth-gear Turn 10 was an
eye-opening experience, as the Mighty Ascot (tm) slid and shimmied on the cold
track. Of course, the other riders were racing on the same track, and everyone
seemed a bit bewildered.
As my race grid was posted, I noticed I was gridded on the second row, despite
my points. I whined a bit to the race officials, and was met with a shoulder
shrug and a "oh well." Apparently, AHRMA's computer crashed, so grids were
filled out by the "braille" method. (Note: requisite racer bitching about
sanctioning body.)
Grid position didn't end up mattering much, as I got a great launch off the
second row, blasting by Mike Van Slyke on the Bare Bones TZ/Rotax directly in
front of me. I was side by side with front-row gridded Chuck Campbell on a
Yamaha 500 down the start straight, and I outbraked him into Turn 1, dropping in
behind class champ Norm Lastovica, also on a Bare Bones TZ/Rotax, who started on
the pole position.
The sun was out and the track was warm, so the traction offered was about as
good as Summit gets -- equivalent to rough ice vs. the freshly Zambonied stuff.
I knew Van Slyke on his slick-shod bike would be all over me soon, so I guarded
the inside line going into the slow Turn 5. Naturally, he passed me on the
outside. He locked up with Lastovica, and the two slowly pulled away from me.
I was turning lap times consistently two seconds a lap faster than my last
Summit race, but I needed another second a lap to hang with the TZ/Rotaxes, and
I just couldn't seem to step it up. I ended up finishing a lonely third, far
ahead of Campbell on the Yamaha in fourth and Gordon Hamilton on an SR in fifth.
Only eight or so riders were gridded.
Sunday looked better as far as weather goes, with the morning sunny and mild.
Unfortunately, just as we rolled to pre-grid -- we were race 7 of 12 -- it
started to sprinkle. They sent everyone back to the pits while we waited out
the weather. One cloud dumped a bit of rain then moved on. The Bare Bones guys
were swapping from rains to slicks and back again. I decided to stay with my
"do everything but nothing well" Dunlop 591s :-) After about 1/2 hour, things
were dry and we went out. Mike Van Slyke on rains, Norm Lastovica on slicks. I
was gridded properly on the front row this time, and got a great holeshot (more
on that a bit later). Norm still motored past me before the first turn, and we
tiptoed through a very slippery Turn 1. Mike Van Slyke passed me between Turns
Two and Three, and passed Norm as well. He seemed to be hooking up very well on
his rain tires. I caught up to Norm, who seemed to be riding slower than usual.
My bike was sliding everywhere, but I was sewing Norm up, which helped me
overcome my terror. :-0 I passed him going into Turn 10 about lap three, but
he just blasted past on the straight. Everytime he looked back, I'd just wave
at him. I kept right on him, but Summit is a one-line track, and he was tough
to pass with so much motor. I finally outbraked him into Turn 1 on lap five,
ran wide off the concrete patch, slid my front tire about two feet, found
religion, promised to lead a good life, and somehow managed to stay upright and
ahead of him. I "put my head down" (tired racer cliche #1) and put some
distance between us. I couldn't catch Mike, who was too far ahead, but I ended
up holding off Norm by a few seconds. I NEV ER slid a bike around so much in my
life! Summit is a very weird track -- it's not bad if it's warm and dry, but
the small amount of rain before our race and the cooler temps (the track was
dry) made a world of difference. Norm said he just never could get his bike to
hook up. This is the first time I've beaten him fairly on the track (except
when he had to ride an SRX 250 at Gingerman) so it felt pretty good.
BUT . . .
I ended up getting docked a lap for jumping the start! It seemed like the
flagman held the green flag FOREVER after the board went sideways. I was
creeping as I had the revs up and the clutch at the engagement point (AHRMA
rules say your rear axle can't be past your starting line) but the guy just
held the flag. I could SWEAR I saw him looking directly at me with a sadistic
grin! Since AHRMA forgot the "meatball" flag, I didn't get the normal
stop-and-go penalty, and was instead docked a lap. (They warned us about this in
rider's meeting.) So I was credited with fifth place. Since John Goodpaster was
standing about three feet from my starting spot, and I was in the direct line of
sight of about half a dozen AHRMA officials, I decided not to argue my "it was
just my lightning fast reflexes" theory and took my lumps.
After the race, Norm gave me his second place plaque, saying I outrode him and I
deserved it! (Of course, he has walls full of them anyway :-)) Pretty classy.
So, Swingin' Singles Racing next moves to Putnam Park for a WERA Vintage and
Regional Sprint weekend May 17-18, then it's off to the wilds of Wisconsin for
the AHRMA National at Road America May 31-June 1.

Subject: VintRR Noise at Sears Point AHRMA National
One of the nice things about the Laguna Seca vintage races last month
was being able to run open exhausts.
I'm wondering if AHRMA has inquired of Sears Point management if they
are going to enforce their usual AFM noise limits for the August
National. It would be nice (and I think a crowd draw/pleaser, as per
the Honda 6, Benelli 4, etc) if we could run on open meggas/chambers.
Sears Point runs some pretty noisy drag cars at the Wednesday night
drag races and I'd think the occasional 135db CR216 Honda might not
be too much more objectionable to the neighbors.
John G., if you could check with the AHRMA office when next you
check in and let us know on this it would be appreciated.
